A young monster who loves baking decides to bake a cake for her grandmother's 247th birthday.

Tomorrow is Grandmonster's 247th birthday, and Tillie has a boo-rilliant idea. She's going to bake a birthday cake! But when Uncle Hairy gobbles up Tillie’s near-Pierrefect Clawberry Snortcake, she’ll rush to bake another. SPLAT! And another. “MY CAKE!” And another. SHRIEK! Baking on her own isn't easy, and Tillie makes many mistakes, learning that with a little patience, care, and determination, she can do just about anything. After all, like star chef Pierre du Monstere says, 'A baker always rises to the occasion!'
